Force and Motion

What is the rate of change of displacement called ?
1. Speed
2. Velocity
3. Acceleration
4. Retardation
If the velocity of an object increases with respect to time, then it is said to be in
1. Constant Acceleration
2. Retardation
3. Uniform velocity
4. Uniform displacement
The measure of the body's ability to maintain its original position
1. Originality
2. Sustainability
3. Stability
4. None of these
Which of the following is a scalar quantity?

2. Acceleration
3. Velocity
4. Speed
The SI unit of acceleration is-
1. m
2. m/(s*s)
3. m/s
4. km/h
Distance travelled by a body in a given time
1. is always positive
2. can be zero or positive
3. is always negative
4. either (a) or (c)
Average speed of a moving object is equal to the magnitude of its average velocity when it travels
1. in a straight line without turning back
2. in a circle
3. back and forth
4. in a zig-zag path
The slope of velocity-time graph gives
1. velocity
2. distance
3. displacement
4. acceleration
If the velocity of a body does not change , then its acceleration is
1. infinity
2. unity
3. zero
4. between 0 and 1
